I bought a MacBook 2 weeks ago and unfortunately some troubles have come up. To start with, for no reason it suddenly shutdown completeley after two hours of use. It wasn't that hot, I mean, compared to other notebooks I've had. So I pay little attention to it. But yesterday while I was trying to upload an image to an email on my hotmail account, it started making a very annoying noise. It sounded like that PowerPoint animation sound of an old typewriter but very very loud. The screen freezed and the image just started to broke.
